An efficient aza-Michael addition of amines to a variety of activated olefins was carried out under solvent free conditions using iodine-alumina as a catalyst at room temperature or under microwave irradiation (in case of solid) in high yield.
reaction yield, and on the other hand, electron-donating group (CH3) has the opposite effect. In addition, crystalstructure of [Ru(p-cymen)Cl(LH,Cl)] was determined by single X-ray crystallography. Hirshfeld surface analysis has been performed to determine the dominate interactions in molecular crystal. Furthermore, density functional, QTAIM and energy calculations have been carried out, to get the detailed

The invention relates to N-substituted lauramides. These compounds have the formula ##STR1## in which R.sub.1 is a benzyl group and R.sub.2 is an alkyl having from 1 to 4 carbon atoms, or R.sub.1 and R.sub.2 form a 4-benzylpiperidino group with the nitrogen atom to which they are bonded, and n=2 to 6, or one of its salts with organic or mineral acids. Application: Preparation of compositions for antiseptic or antimicrobial use, or disinfectants and preservatives, especially in the sectors of pharmacy, cosmetology or agri-foodstuffs.
Compounds, compositions and methods are provided which are useful in the treatment of diseases through the inhibition of sodium ion flux through voltage-dependent sodium channels. More particularly, the invention provides pyrazole-amides and -sulfonamides, compositions and methods that are useful in the treatment of central or peripheral nervous system disorders, particularly pain and chronic pain by blocking sodium channels associated with the onset or recurrance of the indicated conditions. The compounds, compositions and methods of the present invention are of particular use for treating neuropathic or inflammatory pain by the inhibition of ion flux through a channel that includes a PN3 subunit.
